This invention comprises improvements in time checking and recordingapparatus and it relates to apparatus adapted for recording upon charts,cards or paper slips, hereinafter called slips, the attendances andhours of entering and leaving establishments such as offices, shops, andfactories. Apparatus of this kind may also be used for recording thetime spent upon a job, and for other purposes where an accurate recordof time spent is required.

One-object of this invention is to provide an apparatus of the kind inquestion adapted for recording the instant of its operation in anaccurate and indelible manner and by a single operation, either upon onesingle slip or simultaneously upon several slips. The cards and theapparatus may be adapted for operation over weekly periods whereby theregularity of attendance of members of a stat? and the hours of enteringand leaving premises during that week may be accurately and indeliblyrecorded.

A further object of the invention is to provide a time recorder or checkin which only a simple linear measure of time is involved in thecalculation of the time periods elapsing between the start of a job andthe finish, or between the moments of restarting and suspending a workoperation during a period of a' number of days, as for example a Week.

Yet another object is to provide a combination comprising a travellingpunch, a clock mechanism, a transmission operated by the clock impartinglinear travel to the punch,

. whereby the travel of the latter is proportional to the time, and areleasable slip carrier adapted automatically to bring a contained slipon to the punch forthe record to be made.

A further object is to provide for periodic displacements-of the line oftravel of the punch wherebythe path of travel duringa 5 new period isdisplaced from the path followed during the preceding period. Thisdisplacement. of the line of travel may .be

' accomplished either automatically by the action of the clock movementor by hand adjust- .ment.

- Another object is to provide in the combination a slip carrieradapted, at the moment of its release, for striking the punch with aregulatable force suificient for causing the perforation by the punchone or more slips contained in such carrier.

'Another object is to provide a slip holder for use in the carrier, thesaid holder being adapted for receiving and holding the slips with suchaccuracy that the proper disposition of the slips in the carrier isensured without the need for the exercise of any particular skill orprecaution.

The slips to be employed in the apparatus are provided with lines ordivisions representative of time periods and corresponding with the pathof travel of the punch. These lines or chartings may be adequate for oneor several days and usually will be suitable for a period of one week.

The invention will be more fully described with reference to the annexeddrawings forming part of this specification, in which drawings areillustrated suitable practical examples of construction. In the saiddrawmgs:

In Figures 1 and 2, a is the clock mechanism, b is the casing and c isthe dial plate supported above the clock by suitable pillars on thebottom of the casing. A heart cam 4 is fixed on the minute arbor of theclock.

' any The record slips, such as those seen in Figure 4, are receivableby a carrier g swingable about a horizontal axis it upon which is fixedexternally of the casing an operating lever j. The casing is of wood orany other suitable material and is provided in its top and front wallswith rectangular glass panes. In the top there is an opening 20 throughwhich the slips are inserted when the carrier 9 is in its verticalposition.

The slip carrier 9' comprises two plates separated by a space to intowhich'is insertable a slip holder, hereinafter described with referenceto Figures 5 and 6, the said slip I holder being adapted for enabling avery accurate disposition of the slips in the appa; ratus to be obtainedwithout the exercise of undue care or skill. The slip holder has twowings or sides 7 and 8 hinged together at 9 and vertical edge portionsof the wings 7 and 8 come accurately togethervwhen the holder is closed.The wing 7 has near its lower edge projections 10 whilst the wing 8 hasperforations 11 corresponding with these projections. The slip, seeFigure 4, is formed with perforations 12 so dis osed that when they'areentered by the pro ections 10 which are of exactly the same diameter,the said slip is correctly disposed within the holder. The wings of theholder are formed with projections 13 and 14 for bearing against thewalls of the space u in the carrier for ensuring a correct positioningof the holder, within the carrier. The pro ections 13 at one extremityare different from those at the opposite extremity as will be seen fromFigure 5, the projections 14 being flanked on one side by flanges 24 thepurpose of which will be explained.

The dial plate 0 is formed with a slot 2 in which slides a smalltraveller 3 carrying on v top a punch 15, see also Figure 7. Thetraveller 3 is moved along the slot 2 with a uniform movement in suchmannerthat its distance from the arbor of the clock at any moment is ameasure of the time. I For this purpose, the traveller is formed so asto cage a ball 16 at its lower end, as seen in Figure 7', and this ballrolls in a channel 17 formed in the upper surface of a heart cam 4 seenseparately in'Figure 8. The two curves constituting this heart cam arefractions of spirals of Archimedean, curvature of which the equation is,as is known =7cw. The ball 16 is depressed by a spring'18 formaintaining engagement with the channel 17.

With a clock having a twelve hour circle, the traveller 3 advancestowards the centre during six hours and recedes from the'centre duringthe following six hours and so on. The movement thus imparted to thepunch 15 will be too slow for precise records by the punch unless theapparatus be given considerable dimensions. To avoid this inconvenience,an expedient is adopted whereby the traveller has a speed which isdouble that of the traveller seen in Figure 1. In practice, the partsare set so that the punch moves in one direction from six oclock tomidday and in the opposite direction from midday to six oclock p. m. or18 oclock with a 24 hour dial. For successive records during a day, theslips could be inserted facing the operator during the six hours thatthe traveller approaches the centre and could be inserted in the reverseposition during the six hours that the traveller recedes from thecentre.

Referring to Figure 1, it will be seen that the opening 20 has at itsends hinged shutters or flaps 21 and 22. These shutters are formed withnotches 23 which are narrower than the slot opening 20. If the shutter21 to the left is closed down, it is necessary to arrangement avoids anypossible error in the introduction of the slips in the appropriatemanner.

For regulating the apparatus according to the day of the week, forexample, it suffices to advance or recede to a given degree all theclockwork mechanismand the plate 0. For this purpose, this mechanism isplaced entirely upon a movable plate 25 which can slide in the uides 26either by means of a control lever 2 or by any other appropriate knownarrangement (for example an endless thread workin upon a screw fixedsolidly to the plate 25 The arrangement which permits of doubling thespeed of the traveller is as follows, Figure 3 The traveller 3 insteadof carrying directly the punch 15 carries a pulley 27 upon which arepassed in a contrary sense two 1 cords 28 and 29 wound in an inversesense and represented the one in dotted lines and the other by a line ofcrosses. These cords are attached to a framing. surmounting the platerier carries the punch 15. It will be apparent that the speed of thepunch carrier 36 is at traveller 3, but double that of the traveller.

To operate the apparatus, the operator in- Ttroduces the slipholdercontaining the slip into the upper opening 20 of the apparatus.The slip holder fits accurately into the slip carrier g. The operatorthen operates the release in and so frees the lever j keyed upon the anyinstant in a sense inverse to that of the 7 shaft of the slip carrier.The latter then de- V- scends under its own Weight and the punch 15pierces a hole veryneatly in the slip thereby making an indelible mark.

To recover the slip, the operator raises the lever j which becomeslocked again and he then passes his fingers into the openings 40 andwithdraws the slip.

In order to insure the accurate'placing of the slips in the slip holderwhich is essential for securing a correct marking the impression blockhas two circles 41 which are impressed upon the slip and areconsequently situated in an invariable manner in relation to thedivisions of the slip.

The diameter and'the position of the circles. 41 are calculated in sucha manner that the perforations 12 of a diameter slightly smaller shouldbe found entirely within the interior of the circles 41. i v.

A spring seen to the left hand of the axis h in Figure 1' may beprovided for throwing down the slip carrier when the lever j isreleased. Also, a regulator for this spring may be provided.
